Canopy Assimilation (Net Canopy CO2
Flux) - Open System
In order to measure net canopy CO2
flux in an "Open System", a suitable air supply unit is required
for use with our CPY-3 net canopy CO2
flux chambers to accurately deliver controlled ambient air to
the chamber. We supply a Control Interface Module (CIM)
with suitable air supply built directly into it for this
application. Two versions of our Control Interface Module
are available, one with the air supply unit only and another
with both air supply unit and integral CO2
analyzer & humidity sensor for stand alone operation.

Important Ordering
Information for CPY-3 Chambers
When ordering, please include the
following information:
-
Specify Chamber Type (i.e. rigid, semi-rigid)
-
Chamber Dimensions
-
For semi-rigid (Polythene or PET), specify
minimum and maximum heights.
-
CIM type (with or without integral analyzer) and
air supply or Analyzer Type. If user supplied Air
Supply, it's rate.
-
Length of analyzer interface cables and pipes
(2M is standard)

CPY-3 Canopy Assimilation Chambers
Designed for use with our CIRAS EGM & CIM range of
analyzers for measurement of "open system" canopy
assimilation for both low lying and tall vegetation.
All CPY-3's include environmental sensors for
measurement of temperature and PAR. The CPY-3 can
be supplied in a variety of different makes and sizes,
including:
